Iran and U.S. hit tankers in biggest wave of attacks on shipping since war began

(Reuters) – Iran said on Wednesday it had attacked 10 ships near the Strait of Hormuz after the U.S. sank five Iranian oil tankers, in the biggest declared wave of tit-for-tat attacks on shipping by both sides since the start of six-month-old war.

The attacks sent the price of oil surging, with benchmark Brent crude futures breaching $100 a barrel for the first time since July. At least one seafarer aboard a tanker was reported killed and another listed as missing.

Iran also said it had fired ballistic missiles at a base used by U.S. forces in Jordan. Attacks by both sides since the end of August have shattered a month of relative calm, with the U.S. and Iran hitting military, shipping and energy assets.
